I would use less fibers in the tail or antron yarn, even just some stands of uv dubbing. Maybe set the wing back a bit and for a rib just whack off a small piece of different colored thread or floss. Personally I don't really care for biot bodies I tie some and will fish them but I like a fly to last a bit longer. You can get a really cool effect with the ribbing by leaving your tag end of thread long enough to dub a tiny amount of a contrasting color and make nice open even wraps. In the water it really takes on the look of the natural emerging from the shuck.
